Hi, my daughter's new hamster has both a water bottle and a bowl, but seems to prefer his bottle. However, although this is inside an empty toilet roll, he keeps knocking it over. Any suggestions as to how this can be fixed so it remains upright? His tank is actually a glass aquarium so doesn't have any mesh to fix it to. She will not use tape in case he's a chewer. Thank you!
